Fatigue behavior of RC beams strengthened with FRP considering the influence of FRP-concrete interface
Source abstract
Abstract
Abstract As an indispensable component of structure strengthened with FRP, the bond behavior of FRP-concrete interface is very important. In this paper, a theoretical model is established to analyze fatigue behavior of FRP-strengthened RC beam, and the bond-slip relationships are unified into one model. Two failure criteria are proposed according to steel reinforcement rupture and the intermediate crack-induced (IC) debonding. Through the theoretical model, the theoretical results show that the failure mode changes from the steel reinforcement rupture to the IC debonding as the peak loading increases. Therefore, the fatigue life prediction is more accurate by considering the corresponding failure modes.
